Most offices install CCTV once, then never look at the coverage plan again. More cameras gets added when something happens, not because a gap was actually identified. That reactive approach is exactly how blind spots survive for years without anyone noticing, until the one time footage is actually needed and isn't there.
The entrance camera that doesn't cover the door handle
A camera angled to capture faces walking in often misses the door itself, which means it can confirm who entered but not whether the door was propped open, forced, or left unlocked. Entrance coverage needs to capture the door mechanism, not just the faces passing through it.
Side entrances and fire exits, covered "later"
The main entrance almost always gets a camera. Side doors, loading areas, and fire exits often don't, on the assumption they're rarely used. Rarely used doesn't mean never used, and the doors people assume nobody watches are exactly the ones worth watching.
Access control logs that don't match camera footage
A biometric door log tells you who badged in. It doesn't tell you if someone held the door for another person right behind them, a common way access control gets quietly bypassed. Camera coverage at access points closes that gap; the log and the footage should agree with each other, not just exist separately.
Footage nobody can actually reach when it matters
Local-only storage means footage is only available if someone is physically at the office with access to the recorder. If an incident happens over a weekend or while the owner is traveling, local-only storage turns "we have footage" into "we'll have footage on Monday." Remote viewing and cloud backup exist specifically for this gap.
How to actually find your blind spots
Walk the space as if you were trying to avoid every camera, not as if you were a customer. The paths that let you do that are the blind spots. A proper CCTV and access control plan starts from that walk-through, not from a generic camera count, which is exactly what ALAVILI's free audit covers before any hardware gets installed.
